| Abstract: | The reasons of the breaking of wire-line coring drilling pipe are analyzed and the ultrasonic inspection test for wire-line coring drilling pipe is studied. Moreover, the specific detection methods, equipment and process are analyzed. There is practical significance to effectively predict the fracture of wire-line coring drilling pipe and reduce the accidents rate with economic loss reducing. |
